低渗透油田开发调整技术对策研究

低渗透油田有很多特点,比如油气比较多,油气藏类型也很多,分布区域比较广。如果可以比较合理科学的开发低渗透油田,对我国石油开采能够产生极为积极的影响。基于此,主要讨论了目前低渗透油生产的具体特征,使用油藏工程的方法,以此调整技术,让地层能量得以保持,尽量减缓产量递减的情况。并且探索了开发效果评价以及开发政策界限,以此提高油田的采收率,分析了剩余油的分布特征影响因素。

Study on the technical countermeasures for the development and adjustment of low permeability oilfields

low permeability oilfield has many characteristics, such as more oil and gas, many types of oil and gas reservoirs, and wide distribution area. If we can develop the low permeability oil field reasonably and scientifically, it will have a very positive impact on the oil exploitation in our country.Based on this, this paper mainly discusses the specific characteristics of the current low-permeability oil production, using reservoir engineering methods, so as to adjust the technology, so that the formation energy can be maintained, and try to slow down the decline of production. The evaluation of development effect and the limit of development policy are explored in order to improve oil recovery and analyze the influencing factors of distribution characteristics of remaining oil.
